T/ACC Davison said around 30 county lines have been disrupted since 2016.

“When we disrupt a line they either stop coming into Norfolk or significantly reduce their activity,” he said. “They will either disappear or morph into another line in the next borough and reconstitute themselves as a new business, just as we see in the business community.”

Anyone with information about drug dealing in their area should contact Norfolk Police on non-emergency number 101.
